Additional alloys and tempers are available upon request. We can source to your project specifications. If you do not see your alloy or material listed on our platform, please select “Other” and write in that specific material.

Custom Sourced Materials: A variety of custom CNC milled parts, including metal and plastic, options are available for an instant online quote. If you do not see the material stock you are looking for, please choose “Other” under the material drop-down on your quote page and submit for an expert engineering review once you have specified features, tolerances, inspection needs, and quantities required.

CNC Milling Tolerances

Increase offers a range of CNC machining tolerances to suit your unique design requirements, including GD&T callouts. Based on your part’s geometry and chosen material, we can accommodate standard thread sizes, machine custom treads, and reach tolerances of up to ±0.001”. Our standard tolerances for CNC milled metals are ISO 2768-m and ISO 2768-c for plastics.

Description General Tolerance or Standard
Maximum Part Size Milled parts up to 80” x 48” x 24” (2,032 x 1,219 x 610 mm).
Distance Dimensions For features of size (Length, width, height, diameter) and location (position, concentricity, symmetry) +/- 0.005”.
Orientation and Form Dimensions 0-12″ +/- 0.005″, Angularity 1/2 degree. For 24″ and beyond please consult Increase’s Manufacturing Standards.
Precision Tolerances Increase can manufacture and inspect to tight tolerances per your drawing specifications including GD&T callouts.
Minimum Feature Size 0.020” (0.50 mm). This may vary depending on part geometry and chosen material.
Threads and Tapped Holes Increase can accommodate any standard thread size. We can also machine custom threads; these will require a manual quote review.
Surface Finish The standard finish is as-machined: 125 Ra or better. Additional finishing options can be specified when getting a quote.
Edge Condition Sharp edges will be broken and deburred by default. Critical edges that must be left sharp should be noted and specified on a print.

Surface Finishes for CNC Milling

Gain access to quality surface finishing for custom CNC milling parts to remove aesthetic flaws and improve the appearance of your products. We also provide rigid protection and additional resistance and strength to your parts through superior surface finishes.

Anodizing

Anodizing improves corrosion resistance, enhancing wear resistance and hardness, and protecting the metal surface. Widely used in mechanical parts, aircraft, and automobile parts, precision instruments, etc. Materials:Aluminum.

Bead Blasting

Bead blasting results in parts with a smooth surface with a matte texture. Used mainly for visual applications and can be followed by other surface treatments.
Materials :ABS, Aluminum, Brass, Stainless Steel, Steel

Powder Coating

Powder coating is a type of coating that is applied as a free-flowing, dry powder. Unlike conventional liquid paint which is delivered via an evaporating solvent, powder coating is typically applied electrostatically and then cured under heat or with ultraviolet light.
Materials:Aluminum, Stainless Steel, Steel

Electroplating

Electroplating can be functional, decorative or corrosion-related. Many industries use the process, including the automotive sector, in which chrome-plating of steel automobile parts is common.
Materials:Aluminum, steel, stainless steel

Polishing

Polishing is the process of creating a smooth and shiny surface, either through physical rubbing of the part or by chemical interference. The process produces a surface with significant specular reflection, but in some materials is able to reduce diffuse reflection.
Materials:Aluminum, Brass, Stainless Steel, Steel

Brushing

Brushing is a surface treatment process in which abrasive belts are used to draw traces on the surface of a material, usually for aesthetic purposes.
Materials:ABS, Aluminum, Brass, Stainless Steel, Steel

Applications of CNC Milling

  • Rapid Tooling

    Because CNC can be applied to virtually any material, it is perfect for rapid tooling, i.e., creating fixtures or molds.
  • Rapid Prototyping

    The range of materials available, low cost per unit, and speed of production makes CNC a great option for prototyping.
  • End-Use Production

    High-quality finish, vast material options and precise tolerances have made CNC a favorable technology for end-use parts.

    Besides mechanical parts such as aluminum engine house and covers, steel shafts, We also good at the parts with tiny features as light guides and reflectors.
  • Machine Components

    This is a rotating cutter for a mask machines. It is important to make it sharp and in the mean time to keep the condentricity under +/-0.01mm.
  • CNC Milled Adapters

    CNC milled aluminum adapters, tight tolerance for dimension, and angles of the holes, with alodine finish.

CNC Milling Service FAQ

1. Why use CNC milling?

Besides CNC turning, CNC milling is one of the most popular custom manufacturing processes. CNC milling is used for the majority of machined parts because it can handle a wide variety of irregular geometries. It is also an efficient means of mass production once the setup is complete

2. What kind of equipment do you use?

Increase”s facilities contain high-end 3-axis, 4-axis and 5-axis machining centers.

3. Can I combine milling with other processes?

Yes. We can use a CNC machine to mill details, features and text onto parts made using other processes like casting and 3D printing.
